Recording Guitar
It's well worth it to learn the techniques for recording guitar. For a modest investment of time and money, you can:
- Hear yourself and your instrument with new clarity.
- Enhance practice time by playing along with backing tracks or your favorite band.
- Share your music with others.
- Experiment with numerous simulated amplifiers and effects.
- Collaborate with others, even if they're miles from your home.
- Best of all... add fun to your learning!
There are a number of methods for recording guitar and storing or processing the sounds. At some point you'll probably want to get them onto your computer. I'll cover four methods that are affordable and popular. I'll also describe some of the most popular products used for recording guitar at a reasonable price.
The Basic Concepts
Any guitar can be recorded. A guitar that is connected directly to your computer, or other recording device, will provide the cleanest sound, but with a microphone you can record any guitar that produces audible sound.
The key to recording, and later processing, your guitar playing is capturing a full, clean sound.
A 'full' sound is one where the vast majority of the original sound is captured. A 'clean' recording is one that has eliminated most noise. Here are a few tips to help you capture the best possible sound:
- Capture sound with as much volume as possible, but avoid clipping (clipping occurs when the input level is too high, shown by recording level indicators turning red).
- Capture sound at a fast rate, to collect as much sound, and as many subtleties, as possible. CD WAV files, for example, record 16-bits at a time, at a sample rate of 44.1 kHz.
- If using a microphone, eliminate as much background noise as possible. Once you've recorded background noise, it can be difficult to eliminate.
- Leave some silence at the beginning and end of the recording, it can easily be removed later, but if you cut it too close, you might actually cut off part of your performance.

Method One: The Direct Audio-In Connection
The easiest and least expensive method for recording guitar is to connect your instrument directly to the Audio-In port of your computer. The Audio-In port is sometimes called Line-In or Mic-In.
Audio-In ports are typically on the side or rear of your computer, often near the Headphones-Out or other sound ports. The Audio-In port is usually identified with an icon such as a microphone or a circle with two triangles on either side (Macintosh). If you have trouble locating the Audio-In port, consult your owner's manual or the manufacturer's web-site.

To connect your guitar to the Audio-In port you need a special cable or an adapter for your existing guitar cable. Why? A standard guitar cable has a 1/4" phone plug on each end. A standard computer Audio-In port takes a 1/8" stereo plug.
Radio Shack sells a six-foot shielded cable with a phone plug on one end and a 1/8" stereo plug on the other for about $5. It's a great way to test-drive this type of connection. If this method works for you, you might want to invest in a high-quality cable, such as the Monster iStudioLink Instrument Cable, made specifically for connecting and recording guitar.

Once you have this cable, or adapter, here's how to connect your guitar:
 |
Advantages:
- Low-cost
For the connection, all you need is a new cable or adapter. For basic recording, you can use Apple's Quicktime Pro (Mac or Windows) or the Sound Recorder application (included with the Windows operating system).
- Easy
There are few components involved, so it's easy to get started.
Disadvantages:
- Weak signal
Most guitars produce weak output signals. Standard Audio-In ports are not properly equipped to boost this signal, so it may be hard to hear and produce weak recordings.
- Undesired noise
This method is most likely to cause hum (a buzzing sound) or pass along other undesirable noises.
- Delay
The analog signal from your guitar must be converted to a digital form at some point: either in an external processor, like a digital amp, or inside your computer. That conversion takes time. How much time depends on what else your computer is doing, and how fast the processor and components are.
- Only two input channels
An audio-in port has two channels. You can record one stereo input, or two mono inputs. This is not a problem if all you wish to record is your guitar or two mono devices. If you want to add other instruments, or voice, you may need more.
If you're unhappy with the sound quality from this method, try Method Two for recording guitar, the Powered Audio-In Connection.
Method Two: The Powered Audio-In Connection
A direct Audio-In connection may work for you, but most guitars provide a signal that is too weak, and turning up the volume simply produces hum or other undesirable noises when recording guitar.
To solve this problem you need to boost the signal from your guitar. Any audio device that contains a pre-amp (the first stage of amplification) can boost the signal for you.
Many accessories for guitar include pre-amps, so you might be able to try this improved solution for recording guitar without further expense. Look for any guitar accessory (amp-modeler, pedal, drum machine, direct box) with an output labeled "PA Out" or "Line Out".
Dedicated pre-amps for microphone and guitar are a great alternative. They'll provide all the power you'll ever need to drive the Audio-In port. Price, features, and power vary widely. In general, the best tone comes from pre-amps that use tubes. You'll find great units for as little as $50, or you can pay much more for professional rack-mounted units.

Here's what a typical Powered Audio-In Connection looks like:
 |
This method provides some important advantages, but does not solve all of your problems.
Advantages:
- Better signal
Sufficient input signal for quality recording.
- Added capability (varies by component)
Choosing the right accessory can give you additional flexibility and capabilities when playing, including: amp simulators, drum machines, tuners, multiple inputs.
- Modest Investment
A setup like the one shown (not including guitar, cables, and computer) can cost as little as $30.
Disadvantages:
- You're still limited to two input channels
Since the Audio-In port is the bottleneck in the connection, you still have only two input channels for recording guitar and other instruments (the left and right stereo-in channels).
- Delay
The signal is improved by your pre-amp device, but latency (delay) probably is not.
Methods three and four solve both of these problems.
Method Three: An External Digital Recorder
Products such as the Zoom H4 Handy Recorder and the Boss Micro BR Digital Recorder make recording guitar (or any other sound) very easy.
Carry one of these (or similar portable recorders) with you. When you're ready to record, pull it out and switch it on. Record your band, your professor, your practice session, and more. When you get home, connect to your computer and transfer the files. It's that easy.
In addition, these recorders offer many additional features, such as:
- Multi-track recording: Record up to four separate tracks of sound.
- Direct-connect Recording: Guitar or Microphone
- Expandable Memory: up to 1GB for the Boss unit, 2GB for the Zoom
- Amplifier Modeling and Built-In effects
- Portable Drum Machine (Boss only)
- Sound File Playback and Slow-Down: Practice to favorite songs or playback your practice session (Slow-down on Boss only)
- Pre-Amp: USB Direct Connect Audio Pre-Amp & Interface (Zoom only)
- Built-In Tuner: Chromatic tuner for guitar or bass
- Built-In Metronome (Zoom only)

Portable Recorders
Advantages:
- Simple!
No special cables needed for recording guitar. Plug, play, record, then download at your leasure.
- Portable
Small enough to fit in your gig bag, your guitar case, maybe even your pocket.
- Tuner Replacement
Put one of these in your gear bag, and take your old tuner out.
- Effects On The Go
Use the built-in guitar effects, microphone effects (Zoom only) or drum machine (Boss only) to enhance your recording, or just have fun.
- Recording & Post Processing Software (Zoom only)
Zoom includes the limited edition of CUBase software (Windows or Mac) to edit your sound files.
- Multi-track recording
At least four tracks, with more possible through 'virtual tracks' (Boss only) or editing on your computer (both).
- Stereo Microphones For Recording (Zoom only)
Studio quality X/Y pattern condenser mics.
Disadvantages:
- First Generation Products
Many reviewers report great results, but first generation products may create more problems then established versions.
- Memory Cards Add Cost
Prices for memory cards are falling all the time, but adding more memory will drive up your cost.
Method Four: The Powered Digital-In Connection
The best method for recording guitar with your computer is to eliminate the analog components and connect digitally. Here's what you'll need:
- A Pre-Amp'd device with USB or Firewire output.
- A USB, Firewire, or Digital I/O (S/PDIF) cable.
- A USB, Firewire, or Digital I/O port on your computer.
The connection looks nearly the same as for Method Two, above. You'll connect your guitar to the pre-amp'd device, then connect that to your computer. The difference is found in the cable that connects to your computer. Instead of using an 1/8" stereo in cable, you will use a USB, Firewire, or Optical cable. The specific cable depends on the pre-amp you purchase and the ports available on your computer (make certain they match).
These devices are quite affordable. Most provide multiple inputs, many can power dedicated speakers for monitoring, and they frequently include numerous sound effects and/or sound-processing software.
Products range from all-in-one cable devices to powerful systems that produce crisp, clean sound when recording guitar. You can see samples of popular interfaces here.
Advantages:
- Digital Input
A digitized copy of your guitar can be stored, copied, modified in numerous ways, and easily shared with others.
- Reduced Latency
Latency is the amount of time required to convert your guitar's analog signal to a digital signal. When recording guitar to a computer, you want as little latency as possible. Because the external device is designed to convert your guitar's analog signal to digital very quickly, the signal is available to your computer almost instantly.
- Powered speaker outputs
Many of the devices for digitizing your guitar signal have outputs for monitoring sound with external speakers.
- Headphone Output
Another common feature is a headphone output, for when you wish to work without disturbing others.
- Multiple Input Channels
You can connect many inputs, including MIDI instruments, with some of these devices.
- Other Specialty Features
These devices not only make it easier to record guitar on your computer, they offer a wide variety of special features, including: amplifier modeling; balanced output (for direct connection to PA systems); MIDI input; looping; built-in metronome and/or tuner; modeled pedals, special knobs and controls for working with sound-processing software; and, most are compact for travel.
- Digital Sound Parameter Control
It's true that you'll need to play with the various digital sound parameters (such as bit-rate and sampling rate) to determine the best sound for you, but with an external box you control these parameters, not your PC's sound card.
Disadvantages:
- Less Portable
Your setup is only as portable as your computer. If you have a laptop, you might be able to take this on the road, if not, it's a home-based solution.
Recording Guitar Summary
The least expensive way of recording guitar to computer is to connect it directly. You need only a cable with a 1/4" male plug at one end and a 1/8" male plug at the other. You can also use a standard guitar cable with a 1/4" to 1/8" adapter. However, unless your guitar puts out enough power for your sound card the signal will be too weak for practical use. For more information, see Method One, above.
To effectively use an Audio-In port, place a pre-amp between your guitar and the Audio-In port. You'll still need a 1/4" to 1/8" cable, or an adapter. You'll be rewarded with great signal strength, but may still encounter problems with latency and you can use only two input channels at a time. For details, see the write-up of Method Two.
By using an external digital recorder for recording guitar, all of the timing and connection problems are solved, but at the expense of introducing a dedicated device that may, or may not, live up to your expectations. Still, these new devices deserve strong consideration, thanks to their versatility (especially the Zoom H4), and their presence in guitar cases around the world will almost surely increase. For more information see the details under Method Three.
The best method for recording guitar to computer is to use a pre-amplified device with a digital output. You can find devices with USB, Firewire, and Optical outputs. You'll need to ensure that your computer has an input port that is compatible (nearly all computers now have USB, many have Firewire, and the latest multi-media systems include Optical I/O ports. Search for products with "Digital S/PDIF"). You'll benefit from near zero latency, great sound, multiple channels, lots of control over the quality of signal. Plus, many of these products ship with software for recording, effects processing, and amplifier simulation. Read more about Method Four above.
